A strip i^ inches wide along both ends and on one sidewas bent up at right angles to the rest, so that ? box open at the top and alongone side was formed, which measured 11 by 2| inches on the bottom. Thedouble, triangular, carlike projections formed at the two corners were foldedalong the back and secured by means of rivets. The tin was then cut, orslashed, f of an inch deep, i inch distant from either corner on the cuts were also made at the corners, and three equally distant fromeach other and from the cuter edges were made on either end.

GERMINATION STUDIES 61 of tin along the middle of the back and those next to the free outer segmentson the ends were folded in until parallel with the bottom. These act as a shelfon which to rest the next higher tray. The outer and innermost segments atboth ends were bent outward, forming projections which are very useful inlifting the trays. The second segment from the corner at either end was bentout at right angles to the side, and then the outer portion of it was again turnedup until it was parallel with the position which it formerly occupied. These, withthe segments at both corners along the back, which were left erect, prevent thenext higher tray from slipping or sliding. It was found desirable to cut thebottoms of the trays out, since the rapid absorption of heat by the tin has
